The role of interdisciplinary expertise in international law
In our days, international judicial and quasi-judicial bodies are faced with epistemological and methodological challenges in the acquisition and assessment of evidence. Factual knowledge is increasingly searched and acquired through expertise, beyond the competence of international lawyers. As a result, these bodies have integrated scientific, disciplinary and technical methods. Those methodological innovations do not leave international law without echo: the role of interdisciplinary expertise does influence in various ways not only how individual disputes are settled, but also how international law develops. The expertisation of fact-finding can impact on judicial decisions, galvanise State practice, modify the interpretation of existing law, or instigate international law-making. The panel examines these issues, stressing also the role of experts.
